Inventor: YAMAMORI NAOKI
IPC: C09D5/08
Filed: 1984-03-01
Abstract: PURPOSE:To provide an antifouling paint which has excellent adhesion and crack resistance and gives a dry film having a specified glass transition temp., by using a high-molecular organotin compd. as a vehicle. CONSTITUTION:An antifouling paint which gives a dry film having a glass transition temp. of -15-35 deg.C, pref. -5-25 deg.C, is obtd. by using a high-molecular organotin compd. as a vehicle and optionally adding an antifouling agent. When the Tg of the film is higher than 35 deg.C, the film is not flexible and cracked after immersed in seawater, thus causing the peeling or adhesion failure of the film. When Tg is lower than -15 deg.C, the film is not dried and hence the paint cannot be put to practical use. The film can be softened by controlling the Tg of the high-molecular organotin compd. serving as a vechicle or adding a Tg modifier.
